FMC's subsea wellhead systems lead the industry with reliable and cost-effective drilling solutions which meet customer demands for Standard, Slimbore and High-Capacity drilling and production in water depths from a few hundred feet to 10,000 feet or more. In addition to our advanced technology and systems, we provide world-proven weight-set installation, metal-to-metal sealing and multi-function tools. The FMC subsea wellhead family of systems can be configured in a multitude of applications, reducing installation time and money over competitive designs.
Our drilling systems feature
The proprietary metal annulus seal is rated for 15,000 psi service. Gas testing has been successfully completed to 350 F, with the seal maintaining integrity even after cool-down. The metal-to-metal seal is weight set with the hydraulic action of the Single-Trip Tool completing seal energizing and lockdown.
The UWD-15 elastomer seal assembly provides a reliable alternative to metal-to-metal seals. It is rated to the same operating temperature and pressure and is fully interchangeable with the metal-to-metal seal assembly. The proprietary FMC Subsea Drilling Systems’ elastomer expands radially and is preloaded as setting pressure is applied.
Drill-Cutting Injection Wellhead System
The Drill-Cutting Injection Wellhead System is designed for guideline water depths. In order to reach ultra-deepwater depths, the system will be adapted to accommodate a preloaded system and guidelineless operations. Emergency isolation during drilling of the hole for the 13-3/8" casing is facilitated via an isolation sleeve. This design prevents a possible well abandonment situation in the event of leakage of the injection system seals.
